To all-'whom t may concern Be it known that I, the undersigned, IsRAELMONROE CHRIsoo, a citizen of the United States, residing at Bartlett, inthe county of Shannon and State of Missouri, have'invented certain newand useful Improvements in Corn-Planters; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same. v

My invention relates to corn planters and more particularly to thoseknown aswireless checkrow planters, and has for one of its objects theprovision of an actuating rod of simple construction, effective in itsoperation= and thereby dispensing with the necessity for the cumbersomemechanism now in use.

'A further. object of my invention is the provision of means forelevating one of the master wheels for arranging the same in operativeposition at the initial start 'of the planting operation or whennecessary to line up in the field.

Afstillfurther object of my invention is the construction of means fore'liciently throwing the actuating means into and out of operativeengagement.

A still further object of my invention is the provision of means formarking the ground where corn has been planted for the purpose ofstarting the row, keeping in the row and regaining the check row in caseofA being thrown off in the eld. And a still further object of thisinvention is Athe arrangement and construction of the parts thereof,whereby the same maybe readily and-effectivelyattached to any planternow in use andvwithout requiring any changes or alterations in themachine to which my invention is to be attached.

These and other objects will more fullyA appear and the nature of theinvention be more clearly understood bythe construction,

combination and arrangement of the parts as described in the followingspeclficatlon, defined in the appended claims and illustrated in theaccompanying drawings, in which,

Figure l is a side elevation-of'a corn planter, the right handy masterwheel being` removed, showing my invention in its operative positionupon the same. Fig. 2 is a top fragmentary-view of the right `side of aplanter, showing the right master wheel attached thereto. Fig. 3 is afront view of the lower end of the operating lever, show? ing theconstruction of the same and its relative relation to the actuating bar.

I deem: it expedient to here state that only a sufficient portion of acorn planter has been shown in the-drawings for fully illustrating theapplication of my invention to a corn planter, and for the sake ofclearness and convenience.

Like reference,charactersl denote similar parts' throughout theseveral-'views of the drawings, reference being had to the same; ldenotes the frame of a corn-planter, and 2 the furrower vof the machine,and also arranged upon the bottomiof frame 1 and at the rear of thefurrower 2 is the drill 3. Mounted upon the frame 1 is the usual cornhopper 4 positioned above the drill 3` in the usual manner. Arrangedupon the bottom of the frame 1 are the brackets' 5, in which isrotatably mounted the check bar 6, and upon this bar is the rocker arm 7and upon the free end of the rocker-arm is pivotally connected theactuating bar 8 and secured to the rocker armV 7 by the keybolt or othersuitable connection 9.

Arranged upon the frame 1, and adjacent the rear lportion thereof,l arethe journal boxes or brackets 10 through which the axle 11 is` adaptedto revolve, and xedly connected to the end of the axleY 11 and at theright side of the frame 1 is the master wheel 12 having arranged uponthe periphery thereof the markers 13," ositioned thereon indiametrically oppose relation to each other. Rigidly. mounted upon theaxle4 11, and at a pointremote from the master wheel 12 and within theframe 1, is the tappet wheel 14, vprovided with the tappets 15 adaptedfor engagement with the lug 16 arranged upon the actuating rod S, t'oroperating vthe same. The tappets and the markers 13 are so positionedrelative to each other that the markers 13 will accurately mark theground at the corn hill.

Mounted upon the brace bar 17 of the `frame 1 and the gear rod 18, whichis journaled in the brackets 19, is the semicireular rack bar 20,provided with the teeth 21 for a part of the periphery, and at themedial central portion of the rack and upon the pivot 22 thereat ismounted the operating lever 23, the lever being arranged upon the pivot22 approximately intermediate of its ends, the lever 23 being providedwith the handle 24, the spring pressed pawl 25 for engaging the teeth21, and a finger piece 26 for operating the pawl 25. The lever 23 isalso provided at the lower end thereof with the yoke'27 having theroller 28 positioned i between the extremities of the yoke 27 andadapted to revolve upon the bolt 29, the yoke member being of sulhcientlength to provide ample space between the surfaces of the roller 28 andthe head of the yoke 27 to perinit the bar 8 to `freely passtherebetween and adapted to travel upon the antifrictional roller 28during the operation of the actuat ing bar. Also arranged upon the rightside of the fra-me 1 and in proximity to the master Wheel 12 andrearwardly of the axle 11, is the bar 30 provided approximately 'thecentral portion thereof with the elongated slot 31, the bar 30being'pivotally mounted upon the frame 1 through the medium of the pin32 and upon which the bar 30 is adapted to swing andl to travelvertically thereon, through the means of the slot 31, and arranged uponthe upper end of the bar 30 is the segmental rack 33, provided with theteeth 34, and upon which rack is arranged a pivot 35, upon which thelever 36 is adapted to revolve, the lever 36 being also provided withthe handle 37, the spring actuated pawl 33 and the usual finger piece 39for actuating the pawl. The lever 3G is pivoted to the 4rack 33 at a.point slightly remote from the lower end thereof and is provided at thetree end with the pivotal connection 40, into which is mounted the lilik4l, the opposite end of the link 41 being pivotally mounted upon the.trarne 1 by the pivot 42, the pivot 42 being adjacent to the pivot 32whereby the bar 30 and the link 41 are sustained in parallel relation toeach other when the bar 30 is set to operative position. Arranged at thelower end of the bar 30 is the-base plate 43 and also upon the bar 30and above the base plate 43 is the ear 44 to which is attached the chain45 adapted for engagement with the hook 46 arranged upon the rearportion of the frame 1 for holding the bar 30 and the base plate 43 inelevated position under the frame of the machine when the same is not inuse.

47 at a convenient point upon the same, pret erably at thc centralportion of the drill, for the purpose ol providing a point vtoraccurately determining the position of the master wheel 12 when settingthe machine at the end oitl the .rows or when out oi line 'in the .fieldand which indicator provides a fixed point with which one ot' themarkers 13 ot the master wheel 12 `is to register in such manner that ahorizontal plane passing through the indicator 47 also passes throughone'or other of the markers on the side ol the wheel nearest saidindicator thus determining the beginning ot' the dropping operation forspacing the hills of ccrn at a predetermined distance apart.

The many advantages of my invention will be more clearly understood bythe operation of the same as follows: Assuming the planter as set -t'orthe initial start, one of the markers 13 being in registration with theindicator 47, the operating lever 23 being in position shown in fulllines in the draw ings and in which position the actuating bar 8 iselevated in order that the lug 1G ot' the same is in the path ofmovement of the tappets 15 of the tappet'wheel 14, the frame 1, together'with the master wheel 12, being lowered by the forward movement of thelever 3G, each of the respective levers and 3G being held in immovableposition by the engagement of the spring pressed pawls and 38 of therespective levers fixedly engaging the teeth 21 and 34 ot' therespective segmental racks 20 and 33, the master wheel 12 now being incontact with the surface ot' the ground, the planter' is now incondition for operation, as the same is advanced the rotation of themaster wheel 12 being fixed] y connected to the axle 11 necessarilyrevolves the same and at the same time the tappet wheel 14 is revolvedby the axle 11, and upon such movement of the tappet wheel the tappets15 are alternately brought into engagement with the lug 16, therebyforcing the actuating bar 8 rearwardly, this movement rocking therocking arm 7, causes the check rod 6 to slightly rotate and through itsconnections (not shown) with the corn box 4, will cause the grain to bedropped in is now necessary to reset the machine for the return trip andthis is done by depressing the lever 36 and setting the pawl in thelowermost teeth of the rack which downward movement of the lever 36elevates the free end thereof, togetherwvith the link 41, and the samebeing attached to the frame l at the point 42, necessarily elevates'theframe 1 at the righthand side of the machine and at the same time raisesthe wheel 12 out of contact with the ground. Itis to be understood thatthe lever has been advanced in a forwardly direction, as shown in dottedlines, the spring pressed vpawl of this lever being set in the forwardteeth of the rack 20, and by this movement the yoke 27 of the lever 23is carried rearwardly and slightly downwardly, thereby depressing theactuating bar 8, thus causing the lug 16 of the actuating bar to 'bepositioned at a point beyond the path of movement of the tappet 15 ofthe tappet wheel 14, it being obvious that the machine is now in aninoperative condition, or `that it may be termed out of gear, whereuponthe Inaster wheel 12 is now capable of being freely rotated withoutaffecting any of the working parts of the planter and can be readilypositioned wherein one or the other of the markers 13 register with theindicator 47, and after the completion of this operation the machine isthen reset in the manner as stated in the beginning of the operation,and after the machine has been accurately alined with the rowspreviously indicated by the markers 13 through the medium of thesighting means 49.

The bar 30, when not needed for elevating the frame and the master wheelof the machine, is adapted to be swung rearwardly and upwardly andretained in such elevated position by the engagement of the chain 4:5with the hook 46, thecomponent parts of the bar 30 being obviouslyarranged for permitting this movement.

"hile l have here shown and described the master wheel provided withonly two markers and the tappet wheel with only two tappets thereon, ldesire it to be understood 4that I do not limit my invention to thisexact construction. as the master wheel may be provided with any numberot markers as well as the tappet wheel also provided with any number oftappets thereon, the dimensions of either or both being of suchcharactor to meet the exigencies of the case.

I have here shown and described thc preferred embodiment ot myinvention. `but I hereby reserve the right to make such alterations andvariations therein as l may deem expedient, and which do not depart fromthe spirit of this invention or confiict with the scope of the claims.
